Cement is a mixture of different constituents and acts as the main constituent in concrete, Egyptians first manufactured Cementing materials by burning gypsum. The early signs of making concrete. Since then, they started experimenting by adding different materials in the mix to increase the workability of mortar. Do you know? The fact that, hemoglobin acts a plasticizer which helps in increasing workability. But later, they found that it decreases durability. The Portland cement was first manufactured by Joseph Aspdin who is a bricklayer and builder.
It is possible to manufacture different types of cement by changing the percentages of their raw materials. Types of Portland Cement. • Ordinary Portland cement.
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete , mortar , stucco , and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin , and usually originates from limestone. It is a fine powder , produced by heating limestone and clay minerals in a kiln to form clinker , grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of Portland cement are available.
This monograph describes cement clinker formation. The mineral additions to cement are described as are their influence on cement-paste properties. Special cements are also discussed. Cement with atypical properties, such as calcium aluminate, white, low energy and expansive cements are characterized. The last part of the book is devoted to special types of concrete such as self compacting and to reactive powders.
Construction documents often specify a cement type based on the required performance of the concrete or the placement conditions. Certain cement manufacturing plants only produce certain types of portland cement. What are the differences in these cement types and how are they tested, produced, and identified in practice? In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature 2, to 2, degrees Fahrenheit in a rotating kiln, then grinding the clinker to a fine powder.

Cement is a binding material which makes a bond between aggregates and reinforcing materials together. With the development of technology, quality and types of cement have also developed. So there are different types of cement for different construction works.
Every type of cement has their own properties, advantages, and disadvantages. In this article, you are going to learn the most important properties of different types of cement in details. Portland cement is a product obtained by the calcination at a very high temperature, an intimate mixture of correctly proportioned calcareous and argillaceous materials.
Dunuweera, R. We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types. Cement manufacturing processes are associated with emissions of large quantities of greenhouse gases and environmental pollutants. We give below quantitative and qualitative analyses of environmental impact of cement manufacturing. Controlling pollution is a mandatory legal and social requirement pertinent to any industry.
Different types of cement and their uses in construction work as follows Portland blast furnace slag cement. Sulphate resisting cement. Ordinary Portland Cement It is used for all general purposes and widely used for all ordinary concrete work, mortar, plaster etc. It is used in places like Floors of food processing plants, swimming pool, pharmaceutical industries, hospitals, bakeries, public baths and similar places where bacteria and fungi develope.
